At 5:04 a.m. Sunday, a man was seen on the surveillance video walking through a door into a space where the exhibition was being held. Wearing glasses, a black jacket and a camouflage baseball hat, he carefully stepped into the empty room. Seconds later, he's seen rushing out with the artwork in his hands.

A look at some of the recent work of the famously anonymous British graffiti artist Banksy. Banksy's "Love is in the Bin" is unveiled on October 12, 2018, at Sotheby's in London. Originally titled "Girl with Balloon," the canvas passed through a hidden shredder seconds after the hammer fell on October 5 at Sotheby's London Contemporary Art Evening Sale, making it the first artwork in history to have been created live during an auction.

The show's publicist said the surveillance video is real and not a publicity stunt, reported the CBC.

The print had gone missing during the exhibit's setup, a coordinator of the exhibit said in a Thursday news conference, the CBC reported.
